WINMAIL.DAT and TNEFEnableConversion=1

Is it just me, or has anyone else seen an issue with attachments not having the correct file extension after TNEF conversion?

We had a situation yesterday where a supplier was sending automated messages that contained only a winmail.dat file.

After a little research (thanks, forum!) I found and enabled TNEFEnableConversion=1, which converted the winmail.dat upon receipt; but the enclosed attachment had no file extension, so it can’t be easily opened/viewed.

I converted the winmail.dat at http://www.winmaildat.com, and the attachment has an extension.

Has anyone else seen this?

Thanks!
